Concurrency Control Protocol for Nested Transactions in Real-Time Databases
Ekaterina Pavlova, Igor Nekrestyanov · Electronic workshops in computing · 1997
In this paper we consider real-time concurrency control for the nested transaction model. We analyze problems that have pure optimistic and pessimistic approaches. As the solution we propose a hybrid concurrency control algorithm which acts as an optimistic for transactions from different transaction trees and as pessimistic inside a single transaction tree.
